Reaction Features of Nitrosulfodienes of Thiolene-1,1-dioxide Series with Semicarbazide

The influence of the electronic and spatial structure of the diene system of 2-benzylidene-3-methyl-4-nitro-2,5-dihydrothiophene-1,1-dioxides on the result of the reaction with semicarbazide in different media (in ethanol and DMSO) was studied. The structure of the obtained compounds was established by IR, 1 Н, 13 С{ 1 Н}, 1 Н– 13 С HMQC, 1 Н– 13 С HMBC, 1 Н– 1 Н NOESY spectroscopy methods.
